Abstract
Abstract A tackifier composition comprising, as essential components, (a) 100 parts by weight of a polyether having at least one reactive silicon group; (b) from 10 to 140 parts by weight of a phenolic hydroxyl group-containing cyclopentadiene resin which is obtained by copolymerization of 100 parts by weight of at least one component A selected from the group consisting of five-membered ring compounds of the following general formula having conjugated double bonds, and Diels-Alder reaction adducts thereof, in which H is a hydrogen atom, R is an alkyl group having from 1 to 3 carbon atoms, and m and n are each an integer of 0 or at least 1 provided that m + n = 6, with 5 to 200 parts by weight of at least one component B selected from the group consisting of monohydric and polyhydric phenols and alkyl-substituted products thereof; and (c) from 0.1 to 10 parts by weight of a curing catalyst.
