Abstract
A photocurable adhesive composition for glass is disclosed, comprising (A) 100 parts by weight of a polyorganosiloxane having an average compositional formula: ##STR1## wherein R.sup.1 represents a substituted or unsubstituted monovalent hydrocarbon group except for a vinyl group; 0<a.ltoreq.1; 0<b.ltoreq.2; and 1<a+b<3, (B) from 0.1 to 10 parts by weight of an aromatic ketone photo reaction initiator, and (c) from 0.1 to 5 parts by weight of a trialkenyl isocyanurate or a derivative thereof. The composition, when applied between glass plates or between a glass plate and other materials, can be cured with a small curing shrinkage by short-term irradiation of light transmitted by the glass plate. The cured composition exhibits satisfactory adhesion and excellent resistance to moisture and heat.
