PROBLEM TO BE SOLVED: To provide a composite transparency and a method for production thereof.SOLUTION: The colored composite transparency includes a surface at least partially coated with a transparent tinted coating deposited from a coating composition comprising polymer-enclosed color-imparting particles. In other respects, the invention is directed to composite transparencies exhibiting a plurality of hues. The composite transparencies comprise the surfaces at least partially coated with a transparent tinted coating deposited from a coating composition comprising an aqueous dispersion of polymer-enclosed color-imparting particles, wherein the tinted coating has a plurality of thicknesses.
Abstract:
PROBLEM TO BE SOLVED: To provide a composition for a high heat-resistant coating, having excellent workability, by imparting solubility in an organic solvent to a polymer which has an aromatic ring originally insoluble in the organic solvent in the skeleton, which has high rigidity and is excellent in heat resistance (thermal decomposition temperature, thermal expansion coefficient, glass transition temperature, etc.), mechanical strength (modulus of elasticity, hardness of coating, etc.), chemical resistance, water resistance, and so on, and to provide a high heat-resistant film, and a method for producing the same. SOLUTION: The composition for a heat-resistant coating includes an aromatic resin which is formed by introducing a sulfonic acid group and/or a salt of a sulfonic acid group, or a sulfinic acid group and/or a salt of a sulfinic acid group as a substituent to one or more aromatic resins which is/are selected from aromatic polyethers and aromatic polysulfones. Contents of the sulfonic acid group and/or the sulfinic acid group is 1-30 wt.% with respect to the weight of the resin as a whole, and the resin is soluble in organic solvents. The composition for the high heat-resistant coating including the resin is thermally stable at temperatures up to about 280°C, and when the temperature is raised so as to exceed about 300°C, occurrence of SO 2 is recognized and weight reduction is observed.
