Lacquers and molding compositions containing an anti-adhesive character producing and lubricity increasing amount of a polyester-containing polysiloxane corresponding to the formula [Figure] (I) wherein A, B and D each represent －CH3 or －Z－R－Q; Z represents an alkylene group with 1 to 11 carbon atom

Lacquers and molding compositions containing an anti-adhesive character producing and lubricity increasing amount of a polyester-containing polysiloxane corresponding to the formula [Figure] (I) wherein A, B and D each represent －CH3 or －Z－R－Q; Z represents an alkylene group with 1 to 11 carbon atoms, －(CH2)2SCH2－or －(CH2)3NHCO－; R represents an aliphatic, cycloaliphatic or aromatic group containing at least 3 carboxylate ester groups and having an average molecular weight of 300 to 3,000; Q represents a reactive group capable of chemically reacting with a resin component of the lacquer or molding composition; x represents a number from 4 to 150; y represents a number from 1 to 6, in which an average molecule contains at least one group －Z－R－Q and the ratio of the number of －Z－R－Q groups to the number x is from 1:3 to 1:30. A process for imparting anti-adhesive character and increasing lubricity of lacquers and molding compositions by incorporating such polyester-containing polysiloxanes into the compositions as additives is also disclosed.
