    摘要： The present invention is a method of measuring a gonio-spectral reflectance factor to establish a gonio-spectral reflectance factor database available for a personal computer by which a highly-fine realistic 3D computer graphics image can be formed. The method enables colorimetry in a reduced hours in fewer viewing directions compared to the conventional method by executing colorimetry in a plurality of viewing directions selected at random from all the directions that can be viewed by a goniospectrophotometer, said plurality of viewing directions being less than all the directions that can be viewed by the goniospectrophotometer.

    摘要： The invention concerns a method for forming a coating with excellent adhesion, water resistance and appearance which comprises the combination of steps of applying on the hydrophobic surfaces having a surface tension of 35 dyne/cm or less of a substrate a dry surface treatment selected from vacuum plasma treatment, corona discharge treatment and ozonization treatment, coating thus treated surfaces with a dispersion type aqueous coating composition comprising an aqueous varnish of at least one aqueous resin whose 1 wt % deionized water solution has a surface tension of 51 dyne/cm or less and which has a water tolerance of 4 or more, and water insoluble resin uniformly dispersed in fine particles in said varnish, the water insoluble resin having a SP value which is 1.0 to 2.2 lower than that of said aqueous resin, and baking the coating. The present method is specifically useful in the coating of automobile bodies, appliances and other high-quality products.
