An aqueous dispersion which is excellent in storage stability, and can form
a coating film excellent in leveling properties, anti-checking properties,
water resistance, etc., transparent and high in hardness, which is
obtained by mixing and emulsifying (A) at least one selected from an
organosilane represented by (R.sup.1).sub.4-n --(Si)--(OR.sup.2).sub.n, a
hydrolysate of the organosilane and a partial condensation product of the
hydrolysate, (B) a radical polymerizable monomer, (C) an emulsifier and
(D) a hydrolytic catalyst for component (A) to reduce the particle size of
an emulsion, as well as to allow hydrolysis of component (A) to proceed,
and adding (E) a radical polymerization initiator to allow polymerization
of component (B) to proceed, has a concentration of alcohols having a
boiling point of 100.degree. C. or less of 0.1 to 2.0 wt %, and further
contains (F) a component having ultraviolet absorption and/or light
stabilization action as needed.
Uma dispersão aqueous que seja excelente na estabilidade do armazenamento, e pode dar forma a uma película revestindo excelente em nivelar as propriedades, anti-verificando propriedades, resistência de água, etc., transparente e elevado na dureza, que é obtida (A) ao menos misturar e emulsionar selecionado de um organosilane representado perto (R.sup.1).sub.4-n -- (Si) -- (OR.sup.2).sub.n, um hydrolysate do organosilane e um produto de condensação parcial do hydrolysate, (B) um monomer polymerizable radical, (C) um emulsifier e (D) um catalizador hydrolytic para o componente (A) para reduzir o tamanho de partícula de um emulsion, as.well.as para permitir que o hydrolysis do componente (A) prosiga, e adicionando (E) um iniciador radical da polimerização para permitir a polimerização dispersion which is excellent in storage stability, and can form a coating film excellent in leveling properties, anti-checking properties, water resistance, etc., transparent and high in hardness, which is obtained by mixing and emulsifying (A) at least one selected from an organosilane represented by (R.sup.1).sub.4-n -- (Si) -- (OR.sup.2).sub.n, a hydrolysate of the organosilane and a partial condensation product of the hydrolysate, (B) a radical polymerizable monomer, (C) an emulsifier and (D) a hydrolytic catalyst for component (A) to reduce the particle size of an emulsion, as well as to allow hydrolysis of component (A) to proceed, and adding (E) a radical polymerization initiator to allow polymerization of component (B) para proseguir, tem uma concentração dos álcoois que têm um ponto fervendo de 100.degree. O C. ou menos de 0.1 a 2.0 peso %, e contêm mais mais (F) um componente que tem a ação ultravioleta da estabilização do absorption e/ou da luz como necessitada.
