A release coating composition comprises (A) an organopolysiloxane containing at least two (2) ethylenically unsaturated groups, (B) an organopolysiloxane containing at least 2 Si—H groups per molecule, and (C) a hydrosilylation catalyst. If the organopolysiloxane (A) contains only 2 ethylenically unsaturated groups, the organopolysiloxane (B) contains on average more than 2 Si—H groups per molecule. The composition further comprises (D1) a hydrosilylation inhibitor comprising a maleimide of the general formula (I):

##STR00001##

In formula (I), A.sup.3 represents a hydrogen atom or a hydrocarbyl or substituted hydrocarbyl group having 1 to 18 carbon atoms, and A.sup.1 and A.sup.2 each represent a hydrogen atom or a hydrocarbyl or substituted hydrocarbyl group having 1 to 18 carbon atoms. The composition yet further comprises (D2) a second hydrosilylation inhibitor selected from acetylenic compounds, ethylenically unsaturated isocyanates, acetylenically unsaturated silanes and unsaturated dicarboxylic acid diesters or a maleate compound or a mixture thereof.
