Pigment dyed glass fabrics are treated with a bath consisting of (a) 1-8 parts by weight of at least one silane RSiX3 where R is a 1-3C hydrocarbon, aryl, aralkyl or b -prefluoroalkylethyl and X is alkoxy which may be substituted, an acyloxy or dihydrocarbyl-substituted isocyanoxy wherein the acyloxy and dihydrocarbyl radicals contain not more than six carbon atoms or isocyanate, (b) 0.4-4 parts by weight of a compound selected from (1) MX4 where M is Ti or Zr and X is as above and (2) a reaction product of (1) with a b -diketoester or a b -diketone, the ratio of (a): (b) being 1:1 to 10:1 and (c) 100 parts by weight of water, the pH of said bath being 2.5-6. The bath may contain acetic acid and/or zinc acetate. The so-treated fabric may be dried and heated at 150-260 DEG C. The pigment may be bound to the glass fabric by means of an organic resin binder. Examples are given. |
