Title: Colorant for vinyl chloride resin
Inventor: NAKAI TAMAKI
IPC: C08L27/06
Filed: 1989-02-21
Abstract: PURPOSE:To obtain a colorant which can be easily deflocculated and dispersed when mixed under heating and can color evenly a vinyl chloride resin by using a fatty acid amide, a plasticizer and a dye or a pigment as its principal components. CONSTITUTION:A colorant containing a fatty acid amide of an m.p.>=100 deg.C, a plasticizer and a dye and/or a pigment as principal components. When the amide has an m.p.<100 deg.C, there is a disadvantage that the mixer is stained. This colorant has a low melt viscosity upon heating, so that it can be perfectly deflocculated in a mixing step. Because the m.p. of the amide is 100 deg.C or above, the color staining of a mixer can be prevented. Because the amide lowly affects the slipperiness of a vinyl chloride resin compound, the effect to the slipperiness is negligibly small if it is used in a concentration as low as that of a colorant.
