    摘要: Disclosed is a composite composition consisting essentially of a silica polycondensate (A) formed by hydrolysis and polycondensation of one or more alkoxysilane compounds, and a polymer (B) of a radical-polymerizable vinyl compound (B') composed chiefly of at least one monomer selected from the group consisting of acrylic acid, methacrylic acid, acrylic esters and methacrylic esters, the silica polycondensate (A) and the polymer (B) of the vinyl compound (B') being intermingled homogeneously. This composite composition is produced by dissolving the silica polycondensate (A) in the vinyl compound (B') and effecting radical polymerization of the vinyl compound (B'). This composite composition has high transparency, rigidity, toughness and thermal resistance and is hence useful in fields of application where inorganic glass has heretofore been used.

    摘要: Disclosed is a color image-stabilization processing solution for a silver halide color photographic material containing at least one of (a) an N-methylol compound represented by the following formula (I): ##STR1## wherein X represents a group of non-metallic atoms necessary to form a 1H-pyrazole ring or 1H-1,2,4-triazole ring together with the nitrogen atom;and (b) an N-methylol compound satisfying the condition that an equilibrium constant in water at room temperature is 2.times.10.sup.-2 mol/liter or less and a formaldehyde-releasing rate constant is 1.times.10.sup.-5 sec.sup.-1 or more. This solution permits one to dispense formaldehyde and its attendant risks. Also disclosed is a method for processing silver halide color photographic materials using such a solution.
