<p>A pressure-sensitive adhesive curable with active energy rays which is useful as a pressure-sensitive adhesive and pressure-sensitive adhesive sheet. It is liquid at ordinary temperature, undergoes practical crosslinking and curing in the absence of a photopolymerization initiator even when irradiated with visible light or ultraviolet light, and gives a cured coating film which suffers no discoloration and is excellent not only in various pressure-sensitive adhesive performances but in water resistance and heat resistance. The adhesive contains a compound which has two or more maleimide groups represented by the following formula (1) and is liquid at ordinary temperature: (1) wherein R1 represents alkyl, aryl, arylalkyl, or halogeno.</p> |
