Abstract: Provided is a urethane curable composition including: a catalyst (a); a polyol (b) having two or more hydroxyl groups in one molecule; a polyisocyanate (c) having two or more isocyanate groups in one molecule; and silica particles (d) at a predetermined ratio, in which the catalyst (a) is a metal carboxylate represented by a formula (1): M(OCOR)n??(1) where M represents Li, Na, K, Rb, Cs, Mg, Ca, Sr, Ba, Mn, Fe, Co, Ni, Cu, Zn, or Pb; R represents any one of a saturated hydrocarbon group having 1 to 20 carbon atoms, a branched unsaturated hydrocarbon group, an alicyclic hydrocarbon group, and an aromatic hydrocarbon group; and n represents the same number as a valence of M.

Abstract: To provide an antifogging agent composition having excellent sustainability of antifogging performance. An anti fogging agent composition includes a copolymer (A), a polyfunctional blocked isocyanate compound (B), and a surfactant (C). The copolymer (A) is formed of 35 to 90 parts by weight of the monomer (A-1), 5 to 60 parts by weight of the monomer (A-2), and 5 to 30 parts by weight of the monomer (A-3) per 100 parts by weight of the copolymer (A). An NCO/OH ratio obtained by dividing an isocyanate group content (NCO) of the polyfunctional blocked isocyanate compound (B) by a hydroxyl group content (OH) of the copolymer (A) is within a range from 0.1 to 1.5. The surfactant (C) includes 1.00 to 10.0 parts by weight of the anionic surfactant (C-1) and 0.01 to 3.00 parts by weight of the cationic surfactant (C-2) per 100 parts by weight of the copolymer (A).

Abstract: A surface property-improving agent for molded bodies made of polyolefin resins contains 50.0 parts to 90.0 parts by mass of a non-polar wax with a melting point of 50° C. to 100° C. and 10.0 parts to 50.0 parts by mass of a vinyl copolymer obtained by copolymerizing two types of monomers (b1) and (b2). The sum of the non-polar wax and the vinyl copolymer is 100.0 parts by mass. The monomer (b1) is styrene and/or acrylonitrile. The vinyl copolymer contains 0.1 parts to 49.9 parts by mass of the monomer (b1) and 0.1 parts to 9.9 parts by mass of the monomer (b2) wherein the sum of the monomer (b1) and the monomer (b2) is 10.0 parts to 50.0 parts by mass. To 100.0 parts by mass of a polyolefin resin, 0.5 parts to 10.0 parts by mass of the agent is added. The monomer (b2) is a methacryloxypropyl polyorganosiloxane.

Abstract: To obtain elasticity imparting agents for paints comprised of liquid non-aqueous polymer dispersions which, when added to paints, improve the scratch resistance without lowering the acid resistance of the hardened paint film. A liquid non-aqueous polymer dispersion which contains (a) 40-90 percent by weight organic solvent, (b) 10-50 percent by weight particle component comprised vinyl based copolymer which contains 30 percent by weight or more of structural units of formula (1), and (c) 5-40 percent by weight dispersion stabilizer for dispersing the (b) component in the (a) component. In formula (1) R.sup.1 -R.sup.5 are H or methyl groups, m is 0-2, n is 0-10, p is 0 or 1, q is 0-3 and r is 0-3.
