摘要： Disclosed are a magnetic coating material, a magnetic sheet, and a metal compatible tag that have excellent magnetic shielding characteristics against radio waves in the UHF band and do not interfere with a distribution process. A magnetic coating material includes a magnetic filler and a binder resin, wherein the magnetic filler is an Fe—Cr alloy, and wherein in a magnetic sheet formed from the magnetic coating material, complex relative permeability in 860 MHz to 960 MHz has a loss factor tan δ of 0.3 or less and a real part μ′ of 5 or more. Also, a magnetic coating material includes a magnetic filler and a binder resin, wherein the magnetic filler is an Fe—Cr alloy, and wherein a mass ratio of the magnetic filler to a solid content of the binder (mass of the magnetic filler/mass of the solid content of the binder) is from 70/30 to 95/5.

摘要： A method for forming a multilayer coated film includes step (1) of applying an aqueous intermediate coating composition (A), step (2) of applying an aqueous base coating composition (B), step (3) of applying a clear coating composition (C), and step (4) of heat-curing the coated films. The coating composition (A) contains a specific hydroxyl group-containing acrylic resin (a1), a specific polyurethane resin (a2), a specific hydroxyl group-containing polyester resin (a3), a melamine resin (a4), and an active methylene-blocked polyisocyanate compound (a5). A ratio of the resin (a1) to the resin (a2) falls within a specific range. The heat-cured coated film of the coating composition (A) has a specific elongation at break, Young's modulus and Tukon hardness. The coating composition (C) contains a hydroxyl group-containing acrylic resin (c1) and an allophanate group-containing polyisocyanate compound (c2).

摘要： The invention relates to compositions of α,α-branched alkane carboxylic acids glycidyl esters which derived from rosin and or hydrogenated rosin reacted with an epihalohydrin. The above glycidyl esters compositions can be used for example, as monomer in binder compositions for paints or adhesives, as reactive diluent or as acid scavenger. This invention is also about the uses of rosin and or hydrogenated rosin glycidyl ester in combinations with polyester polyols, or acrylic polyols, or polyether polyols.
