歐洲專利檢索Priority number:  WO2016031072

Abstract：Provided are: a pressure-sensitive adhesive composition that adheres well to poorly-adhesive materials and can effectively conceal the surfaces of the materials; and a marking film and a retroreflective sheet that contain a pressure-sensitive adhesive layer formed from such a pressure-sensitive adhesive composition. The pressure-sensitive adhesive composition according to one embodiment of the present disclosure contains: (a) an adhesive (meth)acrylic polymer that contains a carboxyl group and has a glass transition temperature of -50 DEG C or less; (b) a dispersant containing a (meth)acrylic polymer that contains an amino group and does not contain a monomer unit derived from an aromatic vinyl monomer; (c) a tackifier; and (d) at least 15 parts by mass of a titanium dioxide pigment, relative to a total of 100 parts by mass of the adhesive (meth)acrylic polymer that contains a carboxyl group, the dispersant containing a (meth)acrylic polymer that contains an amino group and does not contain a monomer unit derived from an aromatic vinyl monomer, and the tackifier.
