Abstract
Disclosed is a curable polyorganosiloxane composition which comprises: PA0 (A) 100 parts by weight of a polyorganosiloxane having at least two units represented by the following formula in the molecule: ##STR1## wherein R.sup.1 represents an alkenyl group, R.sup.2 represents a substituted or unsubstituted monovalent hydrocarbon group containing no aliphatically unsaturated bond, a is an integer of 1 or 2, b is an integer of 0 to 2, with a+b being an integer of 1 to 3); PA0 (B) a polyorganohydrogensiloxane having a unit represented by the following formula and also having at least 3 hydrogen atoms bonded to silicon atoms in the molecule: ##STR2## wherein R.sub.3 represents a substituted or unsubstituted monovalent hydrocarbon group, c is an integer of 0 to 2, d is an integer of 1 or 2, with c+d being an integer of 1 to 3, in an amount such that the number of hydrogen atoms bonded to silicon atoms may be from 0.5 to 4.0 per R.sup.1 in polyorganosiloxane (A); PA0 (C) 0.5 to 10 parts by weight of a (meth)acryl group-containing polyorganosiloxane comprising: 10 to 40 mole % of units represented by the formula: ##STR3## wherein R.sup.4 represents a hydrogen atom or a methyl group and e i…
