<P>PROBLEM TO BE SOLVED: To provide a releasability-treatment agent which is excellent in that it forms a releasable surface having an appropriate release force, has no selectivity to base materials, as low temperature curing is applicable in forming a release surface, and gives a release surface writable with a pen or the like, and the material of which also contributes to environmental maintenance. <P>SOLUTION: The releasability-treatment agent includes a resin having siloxane segments exhibiting a function to impart releasability. The resin is a polysiloxane-modified polyhydroxy polyurethane resin derived from the reaction of a 5-membered ring cyclic carbonate polysiloxane compound expressed by general formula (1) with an amine compound, wherein R<SB POS="POST">1</SB>is a 1-12C alkylene group (the group may include each element of O, S, or N and/or be linked with -(C<SB POS="POST">2</SB>H<SB POS="POST">4</SB>O)<SB POS="POST">b</SB>-; R<SB POS="POST">2</SB>is non-existent or a 2-20C alkylene group; R<SB POS="POST">2</SB>may be linked with an alicyclic group or an aromatic group; b is a number of 1-300; and a is a number of 1-300). <P>COPYRIGHT: (C)2012,JPO&INPIT |
