| abstract |
A thermoplastic composition comprising a thermoplastic resin and a solid plasticizer, characterized in that the solid plasticizer consists of at least one compound selected among (i) esters having two or more ester groups and obtained from (A) an alcohol (A1) having an alkyl-substituted cyclohexene ring in which the total number of carbon atoms in the substituent is 3 or larger or an alcohol (A2) having a cross-linked ring including a six-membered carbon ring with (B) a polybasic acid, (iia) phosphorus compounds having a melting point of 55 to 100 °C, and (iiia) diesters of (C1) hydroquinone, resorcinol, or catechol in each of which the benzene ring may be substituted by an alkyl group with (D) an organic monobasic acid. The composition is highly safe for human genital organs, and is used as or in a heat-sensitive pressure-sensitive adhesive or a heat-sensitive pressure-sensitive adhesive sheet having excellent blocking resistance. |
