    Abstract: A print paste contains as the binder and as the colouring agent a film-forming copolymer of: (a) at least one dye which bears a polymerisable group; (b) at least one ester of a polymerizable carboxylic acid; and (c) at least one polymerizable hydrocarbon. At least one other comonomer may be included. Component (a) may be replaced by (c) at least one comonomer having a reactive group and (f) at least one dye having a group complementary to the reactive group in (e). Suitable dyes (a) include particularly those of the azo and anthraquinone series, but may also include, for example triphenylmethane dyes. The polymerizable groups are preferably acrylic, acryloylamino, acryloyloxyalkyl, acryloyloxyaryl and vinyl groups. In Example I a coloured copolymer I is prepared by copolymerization of a dye of formula methyl methacrylate, styrene and the butyl ether of methylolmethacrylamide in methyl ethyl ketone with azodiisobutyronitrile as catalyst. Copolymer II is prepared by solution polymerization of vinyl chloride, vinyl acetate and acrylic acid under the same conditions. A print paste is then prepared by dissolving copolymers I and II in methyl ethyl ketone. In Example II a dye of formula acrylonitrile, methyl methacrylate, ethyl acrylate, styrene and itaconic acid are copolymerized in M.E.K. in the presence of azodiisobutyronitrile and a print paste prepared by dissolving this in M.E.K.ALSO:A print paste contains as binder and colouring agent a film forming copolymer of (a) at least one dye which bears a polymerisable group; (b) at least one ester of a polymerisable carboxylic acid and (c) at least one polymerisable hydrocarbon.

    Abstract: A print paste consists of a hydrocarbon liquid phase and an aqueous phase and contains as colouring agent a coloured copolymer prepared from 10 to 70 parts by weight of an ester of (a) acrylic or methacrylic acid, and (b) an aliphatic or cycloaliphatic alcohol having at least six carbon atoms; 1 to 40 parts of a comonomer containing an N-methylol group or N-methylol ether group; 1 to 12 parts of a copolymerizable dye; 4 to 15 parts of an alpha, beta-unsaturated mono- or di-carboxylic acid; 0 to 20 parts of an unsaturated polymerizable hydroxy compound and 0 to 84 parts of one or more other monomers; at least 50% of the free carboxyl groups in the copolymer having been neutralized by ammonia or nitrogenous organic bases. Suitable N-methylol monomers are the alkyl ethers of N-methylol arylamide and N-methylol methacrylamide and of carboxylic imides. Preferred dyes are azo and anthraquinone dyes. The organic base may be an aliphatic or heterocyclic amine. The print paste may include an aminoplast-forming substance and a cure catalyst. In Example 1, a xylene solution of a copolymer formed from alpha - ethylhexyl acrylate, N - butoxymethyl acrylamide, styrene, butanediol monoacrylate, acrylic acid and 2,4,5-trichloro-41-(N-ethyl-N-acryloyloxyethyl)-azobenzene which has been neutralized with dimethyl ethanolamine is mixed with water, NH4NO3 and white spirit. The azo dye may be replaced by 4-nitro-41-(N - ethyl - N - acryloyloxyethyl) - azobenzene or 1 - amino - 2 - isopropylcarboxy - 4 - acryloylaminoanthraquinone. In Example 2, N-butoxymethyl methacrylamide and hydroxy-5 - tertiary butyl - 41 - acryloylaminoazobenzene replace the N-methylol ether and the azo dye used in Example 1. The pastes are used to print fabrics (see Division D1).ALSO:An emulsion-thickened print paste consists of a hydrocarbon liquid phase, an aqueous phase and a coloured copolymer which has been prepared from: 10 to 70 parts by weight of an ester of (a) acrylic or methacrylic acid and (b) an aliphatic or cycloaliphatic alcohol having at least six carbon atoms; 1 to 40 parts of a comonomer containing an N-methylol or N-methylol ether group; 1 to 12 parts of a copolymerisable dye; 4 to 15 parts of an alpha, beta-unsaturated mono- or di-carboxylic acid; 0 to 20 parts of an unsaturated polymerisable hydroxy compound; and 0 to 84 parts of one or more other monomers; at least 50% of the free carboxyl groups in the copolymer having been neutralised by ammonia or nitrogenous organic bases.

    Abstract: Expanded polyamides are produced by heating a mixture of (A) one or more lactams having seven to fourteen ring members, (B) one or more alkaline catalysts, (C) one or more activators and (D) agents which under the prevailing conditions of polymerization volatilize or decompose with the evolution of gas thereby causing the polymerization product to expand, in the absence of substances containing or forming hydroxyl groups to temperatures above the melting point of the lactam and not more than 200 DEG C. and polymerizing the melt with expansion in the presence of 0.05 to 5% by weight of calcined gypsum with reference to the total weight of the polyamide forming materials. Lactams which are suitable are those of omega-aminocarboxylic acids such as caprolactam, oenantholactam, capryllactam, caprilactam and laurolactam. C-substituted lactams, e.g. 4-isopropylcaprolactam and lactams having chain-branching or cross-linking effects, e.g. alkylene-bis lactams may also be used. Suitable alkaline catalysts are metals such as sodium, potassium and calcium or compounds of these metals such as potassamide, sodium alcoholates and sodium hydroxide, organometallic compounds and especially alkali lactamates. Specified activators are acyl-lactams, monoisocyanates, polyisocyanates, acid derivatives such as carboxylic acid halides, esters or anhydrides, but particularly substituted ureas, thioureas, guanidines and urethanes. Examples of these are hexamethylene-1,6-biscarbamidocapryllactam or phenylcarbamidocaprolactam. Suitable expanding agents are aliphatic and cycloaliphatic hydrocarbons such as hexane, octane and cyclohexane, aromatic hydrocarbons such as benzene and toluene and straight-chain and cyclic ethers such as dibutyl ether and dioxane. Liquids having low boiling points, e.g. pentane may be used under pressure. Solid compounds, such as azoisobutyronitrile, benzene sulphonic acid hydrazide and arylsulphazides may also be used. Dyes, fillers and stabilizers may also be incorporated in the mixture.
