Abstract: A printing ink based on mineral oil contains, as a binder, a mixture ofA) from 10 to 50% by weight of an alkyd resin having a hydroxyl number of from 40 to 260 and an acid number of from 10 to 70 andB) from 50 to 90% by weight of a reaction product of rosin and a phenol/formaldehyde condensate.The printing inks are used in the sheet offset printing process.

Abstract: Elastomeric thermoplastic molding materials contain(A) from 5 to 50 parts by volume of a partially or completely crystalline thermoplastic polymer having a melting point of above 160.degree. C., as a coherent phase, and(B) from 95 to 50 parts by volume of one or more crosslinked elastomeric polymers which are prepared by emulsion polymerization, are dispersed in the component A and have a glass transition temperature Tg of below -10.degree. C., the sum of A and B being 100 parts by volume, with the proviso that the mixture of A and B has a Vicat softening temperature, measured according to DIN 53,460, which is 5.degree.-40.degree. C. lower than that of the component A, with or without(C) effective amounts of conventional assistants.
