塗膜厚みの質感への影響

Abstract

6色相で, 光沢度一定で透明塗装量の異なるサンプルをそれぞれ6点ずつ作成した。標準サンプル2点を加え, 色相ごとに女子学生40名に提示し, 塗装質感を順位法で測定した(塗装質感 : 光沢感・透明感・深み感・肉持ち感・金属感・平滑感・シルキー感)。いずれの質感も塗装量の増加に従い増加した。色別に質感を塗装量に対しプロットすると, 相関係数>0.8の単回帰直線が成立した。またその傾きは色に関係なく一定であった。最も塗装量の影響を受ける質感は透明感であり, 光沢感や深み感ではその影響が小さい。

Six color chips were coated transparent vernish to obtained six steps of the amount in each color. Effects of thickness of coated layer on perceived qualities were studied by means of a rank test of 40 girl students (qualities, i.e. gloss sense, transparent sense, deepness sense, thickness sense, metallic sense, planarity sense, silkiness sense). The qualities increased with increasing the vernish amount. When the quality parameters were plotted against the amount of the vernish, good linear relationships were obtained in each color with high correlation coefficients > 0.85. In each quality, a slopse of the relation is equal to each other color. The transparent sense is the most affected by the amount. On the other hand, the effect on the gloss sense and deepness sense are smallest in the other senses.
