1. A radiation-curable release composition, comprising:

  • (A) an organopolysiloxane represented by the formula
    
    
    space="preserve" listing-type="equation">RSi(CH.sub.3).sub.2 --O--(Si(CH.sub.3).sub.2 O).sub.n (Si(CH.sub.3)(R)O).sub.m Si(CH.sub.3).sub.2 R (I)wherein in Formula (I), each R is --R1 --O(O)C--C(R2)═

    CH2, --R1 --O--C(R2)═

    CH2 or ##STR4## R1 is a hydrocarbylene group;

    each R2 is independently hydrogen or a methyl or ethyl group;

    m is a number from 1 to about 15; and

    n is a number from about 50 to about 300; and

    (B) an organosiloxane polymer represented by the formula
    
    
    space="preserve" listing-type="equation">(R.sub.3 SiO)(Si(CH.sub.3).sub.2 O).sub.n (SiR.sub.3) (II)wherein in Formula (II), each R is independently a hydrocarbon group and n is a number in the range of about 1000 to about 20,000.
