Abstract: A combined release coating and backsize for pressure-sensitive adhesive tapes comprises a cured film formed by heating a mixture of a polyester of a fatty acid having 16 or more carbon atoms with an epoxy resin having an epoxide equivalent of 225 to 2,400 and being the reaction product of a polynuclear, poly-functional phenol and an epihalohydrin, an alkylated melamine-aldehyde or alkylated urea-aldehyde resin in an amount not exceeding 75% by weight of the total and an acidic catalyst comprising an alkyl acid phosphate in an amount not exceeding 55% by weight of the total or a mixture thereof with phosphorous or hypophorous acid. The examples describe reactive compositions comprising lauryl acid orthophosphate and:- (I) as stearic acid modified epoxy resin and a butylated melamine-formaldehyde resin; (II) a behenic acid modified epoxy resin and a butylated melamine-formaldehyde resin; (III) a behenic acid modified epoxy resin, a butylated melamine formaldehyde resin and phosphorous acid; (IV) a stearic acid modified epoxy resin and an alkylated urea-formaldehyde resin and (V) a behenic acid modified epoxy resin and a butylated urea-formaldehyde resin. The compositions may also include dyes, pigments, fillers, thickening agents, diluents, solvents, or phenol-aldehyde resins.

Abstract: 818,842. Pressure-sensitive adhesive tapes. PERMACEL-LE PAGE'S Inc., [formerly PERMACEL TAPE CORPORATION]. Aug. 16, 1955 [Aug. 17, 1954 (2)], No. 23626/55. Class 140. A normally tacky and pressure-sensitive adhesive tape or sheet comprises a pressuresensitive adhesive united to one surface of a cellulosic flexible backing film, and united to the other surface of said backing a continuous mirror coating, that is, a smooth glossy and fully transparent coating, of a substantially wax- and plasticizer-free composition in which there is present at least a major proportion of at least one of the following materials: polyvinyl alcohol, carboxy methyl-, hydroxy ethyl-, methyl- and nitro-cellulose, glue, casein, or a lower alkyl methacrylate polymer having not more than six carbon atoms in the alkyl chain, and, applied directly to the continuous mirror coating, resinous binder ink impressions. The backing film may be of cellulose acetate or regenerated cellulose, which may be plasticized, e.g. with a liquid ester such as dibutyl dioctyl or dimethoxyethyl phthalate glycerine or a glycerine substitute such as a water-soluble glycol, or combinations of films with strands, e.g. of cellulose acetate, fibres, fibre webs, e.g. paper, or non-woven fabric. The backing film may be primed, e.g. with a mixture, of butadieneacrylonitrile and butadiene-styrene as in Specification 689,667, rubber latex, synthetic rubber latex-polyvinyl alcohol as in Specification 554,019, rubber rosin, such as a mixture of latex crepe rubber and pine pitch or wood rosin, prior to coating with the pressuresensitive adhesive. Specified adhesives contain crepe rubber, dehydrogenated rosin, smoked rubber, butadiene-styrene, phenol modified terpene resin, oil modified phenolic resin, hydrogenated rosin glyceride, alkylated polyhydroxy phenol, lecithin, lanolin, hydrogenated coumarone indene resin, fillers, e.g. zinc oxide, aluminium hydrate, and titanium dioxide, antioxidants and pigments. The mirror coating may also contain polyvinyl acetate, polyvinyl butyral and tri - ethylene - glycol - di - 2 - ethyl-butyrate. The ink may be based on a binder such as shellac, ethyl cellulose, and nitrocellulose, and may be dissolved in lower aliphatic alcohols or esters containing not more than six carbon atoms in the chain.

Abstract: A copolymer of 40-80 per cent of a higher alkyl acrylate or methacrylate, wherein the alkyl radical has at least 12 carbon atoms, and acrylic or methacrylic acid, is used in the production of low-adhesion coatings on films. The (meth)acrylic acid can be replaced in part by acrylonitrile or methacrylonitrile. Coating may be effected from organic solution or aqueous emulsion. In an example, octadecyl acrylate and acrylic acid in the weight ratio 3 : 2 are dissolved in ethyl acetate, oxygen is removed, a small quantity of benzoyl peroxide is added, and the mixture polymerized at a temperature increasing from 50 DEG to 71 DEG C. To prevent gelation, a little water may then be added. For the production of an aqueous dispersion, there is added to the ethyl acetate solution, propanol and water, and a relatively small amount of p morpholine. The organic solvents are then distilled off under vacuum.

Abstract: 302,588. I. G. Farbenindustrie Akt.- Ges. Dec. 17, 1927, [Convention date]. Single coatings.-In adhesive strips of paper or fabric coated with gum or rubber, the side of the material not coated with adhesive is coated with a cellulose ester, mixed ester or ether-ester, of a higher fatty acid. Unrolling of a roll of the material is thus facilitated, as the sticky surface does not adhere to the reverse side of the strip. The adhesive power of the gum or rubber is not affected. Cellulose laurate is stated to be particularly suitable for the coating.
