The present invention relates to a pressure-sensitivenadhesive curable with active energy beams, which is useful asna pressure-sensitive adhesive and pressure-sensitive adhesivensheet. It is liquid at ordinary temperature, undergoesnpractical crosslinking and curing in the absence of anphotopolymerization initiator even when irradiated withnvisible light or ultraviolet light, and gives a cured coatingnfilm which suffers no discoloration and is excellent not onlynin various pressure-sensitive adhesive performances but innwater resistance and heat resistance. The adhesive contains ancompound which has two or more maleimide groups represented bynthe following formula (1) and is liquid at ordinaryntemperature:n nwhere in formula (1), R 1 represents alkyl, aryl, arylalkyl, ornhalogen. |
