Recording material
专利汇可以提供Recording material专利检索，专利查询，专利分析的服务。并且PURPOSE:To prevent the fouling of the ground of a recording sheet by using a specific substituted phenol derivative compound as a developer for a recording material. CONSTITUTION:A colorless or light-colored color former and a color developer are mixed and ground to prepare a dispersion. In this case, a specific substituted phenol derivative compound of the formula (where R1, R2 and R3 are each H, a halogen atom, or a C1-C8 alkyl group), e.g., 2-(4-hydroxyphenyl)-2-(4'-aminophenyl) propane, etc., is used as a developer in a recording paper. A combined use of the developer with a black color dye, e.g., 3-diethylamino-6-methyl-7-anilinofluoran, etc., gives a particularly raised thicker color-developing effect. In this case, 1- 95pts.wt. developer is used on the basis of 1-15pts.wt. color former and 1- 40pts.wt. binder. In the recording material thus obtained, less fouling occurs in the ground and also the degree of natural coloring under a high temperature and humidity conditions is also less.，下面是Recording material专利的具体信息内容。
