    Abstract: The invention relates to a thermoplastic molding material of an elastomeric polymer A, a shell B grafted to the polymer A, and a copolymer C as rigid matrix. The amount of polymer A is 1 to 25 percent by weight based on the weight of A + B + C. It has a glass transition temperature, Tg, of less than 0.degree.C and an average particle size of 200 to 500 nanometers ( d50 value of the integral mass distribution) and is composed of: 50 to 99.9 percent by weight of at least one alkylacrylate with 1 to 8 carbon atoms in the alkyl radical and 0.1 to 5 percent by weight of a polyfunctional monomer which has a crosslinking action. Grafting shell B represents 5 to 40 percent by weight based on A + 9 + C and is composed of at least one of the monomers of the group of b1 ) vinylaromatic monomers, and b2 ) the ethylenically unsaturated monomers. Grafting shell B is prepared in two stages with 30 to 10 percent by weight of the monomers b1 being used in the first stage, and 30 to 70 percent by weight of a mixture of monomers b1 and b2 in a weight ratio of 90:10 to 60:40 being used in the second stage. Copolymer C is added in an amount of 35 to 94 percent by weight based on A + B + C and consists of a vinylaromatic monomer and an ethylenically unsaturated monomer. The molding material may contain commonly used additives in effective amounts and is used for the prepara--tion of molded parts.

    Abstract: The invention comprises pigment dyes of the formula wherein R1 is H, R2 is H, Cl or CH3, or R1 and R2 together complete a naphthalene ring, R3 is H, Cl or CH3, A is Ca or Ba, B is Mg, Ni, Co, Fe, Al or Cr, x is from 70 to 99.5, y is from 0.5 to 30, x + y is 100 and n is the valency of cation of B. They may be obtained by reacting an azo dye of the formula in an aqueous medium at temperatures up to 100 DEG C. with Ca or Ba salts and with Mg, Ni, Co, Fe, Al or Cr salts, the ratio of Ca or Ba salt or Mg, Ni, Co, Fe, Al or Cr being from 99.5 : 0.5 to 70 : 30 based on equivalent weights. Examples are given for the production of the lakes.
