Abstract: A compsn. for colouring PVC and PVC pastes contains (a) 5-60 (15-35) wt % of a finely divided pigment, (b) 30-94 (60-80) % of a softener, and (c) 2-25 (5-15)% of a copolymer of vinyl chloride (I) and vinyl isobutyl ether (II) in molar ratio I:III of 75:25-80:20. (a) may be (in)organic, e.g. Cr yellow, Pb molybdate, Cu phthalocyanine, and pigments of the condensed anthraquinone, quinacryidone and azo series. The amt. of organic pigment is esp. 15-35 wt %. (b) include mono- and diesters of phthalic acid, bis-(2-ethylhexanol) adipate and bis-isodecanol adipate. The copolymer (c) has X value 35-39. The compsn. is easy flowing at low pigment concn. A mixt. contg. 15-25 wt % pigment is non-thixotropic, can be pumped, and can be metered automatically. Complete dispersion of the pigment is achieved.
