Aqueous dispersion for use in paper coating contains hydrophobic, low-mol. wt. substance, e.g. oil-soluble fluorescent dye, and ethylene copolymer wax based on ethylene and unsaturated acid, e.g. methacrylic acid

摘要

Aqueous dispersion of hydrophobic, low-mol. wt. organic substances (A), contains ethylene copolymer wax(es) (B) comprising 60-99.5 wt% ethylene and 0.5-40 wt% unsaturated carboxylic acid units. Independent claims are also included for (1) a method for the production of such dispersions by mixing (A) with (B) and dispersing the mixture in water (2) paper coating materials containing such dispersions (3) paper containing oil-soluble fluorescent dyes (4) paper treated with the above coating materials.
