To provide an adherence substance which has a low viscosity and good coatability, can be made solvent free, is less likely to undergo an increase in the adhesive strength with time and has good adhesion to an adherend while the adhesive strength is low, is excellent in removability and has a good wettability. n An adherence substance which is obtainable by curing a curable composition comprising a silyl group-containing polymer (S) represented by the formula (1) and which has a peel adhesive strength of at most 8 N/25mm:n nin the formula (1), R 1 represents a t-valent residue derived from a (mono)polyol; Q represents a bivalent group formed by a reaction of a terminal group selected from a hydroxy group, an amino group, an isocyanate group, an allyl group, an acryloyl group and a methacryloyl group, with a specific silyl compound; R 3 represents a monovalent organic group; X represents a hydroxy group or a hydrolyzable group; Y represents a bivalent group containing an ester linkage or a bivalent group containing an ether linkage; a represents an integer of from 1 to 3; r represents an integer of from 1 to 1,000; and t represents an integer of from 1 to 8. |
