Abstract:
Disclosed is an active energy ray curable hot melt silicone composition that is non-flowable at 25° C. and has a viscosity of 1,000 Pa·s or less at 100° C. The active energy ray curable hot melt silicone composition comprises: (A) a mixture of (A1) an organopolysiloxane having an aliphatic unsaturated bond-containing organic group and (A2) an organopolysiloxane optionally having an aliphatic unsaturated bond-containing organic group, (B) a compound having at least two mercapto groups in a molecule, and (C) a photoradical initiator. A cured product and a method of making a film are also disclosed.
