摘要：
The present invention relates to an ultraviolet-curable pressure-sensitive adhesive composition including (a) a monomer component containing 70 to 99 wt % of an alkyl (meth)acrylate with the carbon number in the alkyl group being 1 to 20 and 1 to 30 wt % of a polar group-containing vinyl monomer, (b) at least one polyfunctional (meth)acrylate having four or more (meth)acryloyl groups within one molecule and having an acryl equivalent of 150 or less, in an amount of 0.01 to 0.1 parts by mol based on 100 parts by mol of the monomer component, and (c) a photopolymerization initiator; an ultraviolet-curable pressure-sensitive adhesive sheet using the same; and a process for producing the same.
