Zusammenfassung: | To provide a painting composition capable of showing visibility by coloring when painted and reducing the visibility by self-action in a process dried at normal temperature when forming a painting film, and including the (partial) hydrolysate of a silicate compound forming the painting film excellent in hydrophilicity and stain resistance.SOLUTION: The painting composition comprises (A) 30-80 parts of the (partial) hydrolysate of a silicate compound represented by the following formula (1), (where, R1-R4 show a C1-8 organic group and may be the same or different from each other, and n shows an integer of 1-50.), (B) 10-60 parts of a metal chelate compound and (C) 5-40 parts of a binder component. (where, a "part" represents "pts.wt. of an active ingredient".)SELECTED DRAWING: None
【課題】塗装時においては発色によって視認性を示す一方、塗膜形成時においては、常温での乾燥の過程で、自己作用によって前記視認性が低下すると共に、親水性及び耐汚染性に優れる塗膜を形成するシリケート化合物の(部分)加水分解物を含有する塗料組成物の提供。【解決手段】(A)下記式(1)で表されるシリケート化合物の(部分)加水分解物30〜80部、(式中、R1〜R4は炭素数1〜8の有機基を示し、これらは互いに同一のものでも異なるものであってもよい。また、nは1〜50の整数を示す。)(B)金属キレート化合物10〜60部、(C)バインダー成分5〜40部、を含有する塗料組成物。(ここで、「部」は「有効成分の重量部」を表す。)【選択図】なし |
