The present invention provides a photocurable pressure-sensitive adhesive composition which has sufficient adhesion before being irradiated with light, and after being irradiated with light, keeps a sufficient pot life and has a short cure-completion time at a room temperature. A cured product produced from the composition has high adhesion force to adherends difficult to be attached, and excellent durability. The photocurable pressure-sensitive adhesive composition comprises a crosslinking compound (A) that is crosslinkable by the action of a base, a photobase generator (B) which becomes active upon light irradiation to generate a base, and a tackifying component (C).

A Novel Negative-working Photoimaging Material Based on a Base-amplifying Silicone Resin Tethering Phenylsulfonylethyl Groups
We have developed a base-sensitive silicone resin tethering phenylsulfonylethyl units as base-amplifying groups showing high thermal stability. The resin underwent a base proliferation reaction autocatalytically to generate amino groups on its side chains, which accelerated the base-catalyzed hydrolytic condensation of residual ethoxysilyl units in its main chain. Furthermore, a film of the resin sensitized with a photobase generator provided a negative-working photoimaging material with a high sensitivity.

To provide such a base multiplying agent capable of being used for crosslinking reaction, for example of a epoxy compound and the like, that generates another base by action of a base, and can efficiently perform base multiplying reaction, and a base-reactive curable composition using the base multiplying agent.
The base generating agent of the invention is represented by the following formula (1):
(In the formula (1), X represents a hydrogen atom, a substituted alkyl group or an unsubstituted alkyl group; Y represents a substituted or unsubstituted alkylene chain; and n represents an integer of from 1 to 4.)
