PROBLEM TO BE SOLVED: To provide a curable resin composition for a coating of an automobile interior material, the composition excellent in contamination resistance and easily handled.SOLUTION: The curable resin composition for a coating material comprises a silicone-modified vinyl polymer (A) having a polysiloxane group, a hydrolyzable silyl group and a hydroxy group, and a polyisocyanate compound (B), characterized in that: the silicone-modified vinyl polymer (A) is obtained by copolymerizing monomers containing vinyl compounds (c) containing a hydroxy group by 10 to 40 wt.% with respect to the entire monomers; and the polymer (A) has a glass transition temperature of 30 to 70°C.
Abstract:
PROBLEM TO BE SOLVED: To provide a moisture-curing single-component composition which is based on a polymer containing a silane group, can be produced with a simple method without using a toxicologically unstable material, has a long storage life in the absence of water, is low in viscosity, and comes into contact with moisture to be cured and to give a good crosslinking material with elasticity, and is not based on water. SOLUTION: The moisture-curing one-pack composition has at least one polymer which has a 3-(N-silylalkyl)aminopropeonic acid ester group and is expressed by formula (I), wherein at least one polymer is prepared to be used.

Abstract:
PROBLEM TO BE SOLVED: To provide a hydrophilic composition forming a hydrophilic coating film having excellent scratch resistance and antifouling property without being hybridized with a sol-gel. SOLUTION: The hydrophilic composition contains a hydrophilic polymer (A) having two or more hydrolyzable silyl groups in a molecule, and a catalyst (B). The surface ζ-potential of a coating film obtained by coating and drying the hydrophilic composition is within the range from -15 mV to 10 mV. COPYRIGHT: (C)2010,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a hydrophilic member, provided with a hydrophilic film, which is excellent in fogging resistance, contamination resistance, abrasion resistance, and especially water deposit attachment resistance on the surface of a support. SOLUTION: The hydrophilic member comprises the hydrophilic film formed on the support. The hydrophilic film is formed of hydrophilic film forming composition containing (A) hydrophilic polymer including Si, and (B) metal complex catalyst. Silanol groups existing on the surface of the hydrophilic film are partly or wholly converted into hydrophilic groups other than the silanol groups. COPYRIGHT: (C)2009,JPO&INPIT
