Abstract
(EN)
This grain finish leather-like sheet includes a fiber substrate and a polyurethane surface coating membrane laminated on a surface of the fiber substrate directly or with another polyurethane layer sandwiched therebetween, wherein: the polyurethane surface coating membrane includes a diketopyrrolopyrrole red pigment and/or an α-type phthalocyanine blue pigment, and further includes a clear polyurethane film layer that coats the polyurethane surface coating membrane; and the color difference series evaluation performed on the grain finish leather-like sheet using a gray scale is at least grade 4 to 5, the evaluation being carried out by dropping 0.03 g of oleic acid on a surface of the clear polyurethane film layer and then, using a crockmeter, reciprocating a white cotton cloth 100 times.

L'invention concerne une feuille de type cuir grainé qui comprend un substrat de fibre et une membrane de revêtement de surface de polyuréthane stratifiée sur une surface du substrat de fibre directement ou avec une autre couche de polyuréthane prise en sandwich entre ces dernières : la membrane de revêtement de surface de polyuréthane comprenant un pigment rouge de dicétopyrrolopyrrole et/ou un pigment bleu de phtalocyanine de type α, et comprenant en outre une couche de film de polyuréthane transparent qui recouvre la membrane de revêtement de surface de polyuréthane ; et l'évaluation de série de différence de couleur effectuée sur la feuille de type cuir grainé à l'aide d'une échelle de gris étant au moins de 4 à 5, l'évaluation étant réalisée par dépôt de 0,03 g d'acide oléique sur une surface de la couche de film de polyuréthane transparent, puis, à l'aide d'un vérificateur de résistance au frottement, par réalisation d'un mouvement de va-et-vient d'un tissu en coton blanc 100 fois.
