摘要： PURPOSE:To obtain a new odorless aromatic diisocyanatoindane derivative, usable as a raw material for polyurethane resins 6r polyurea resins in various fields such as foams, elastomers, synthetic leathers, adhesives and films with hardly any toxicity such as contact dermatitis and excellent in stability with time. CONSTITUTION:An aromatic diisocyanatoindane derivative expressed by formula I (R1 and R2 are H or 1-10C alkyl), e.g. 5,7-diisocyanato-1,1-dimethylindane. The compound expressed by formula I is obtained by reacting a diaminoindane derivative expressed by formula II or its salt with phosgene. Since the compound expressed by formula I has respective isocyanate groups hindered with the adjacent alkyl groups and an indane skeleton, a moderate curing rate is obtained when used in a polyurethane. The reactivity can be adjusted by selecting the alkyl groups. Resins obtained therefrom have mechanical strength and resistance to heat and UV.

摘要： PURPOSE:To obtain an aqueous suspension of polyvalent metallic compound of co condensed salicylic acid resin containing a stable and high-degree solid which can be preserved for a long time without precipitation or flocculation by dispersing specific sulfonated styrene maleic acid polymer, in the presence of salt, into water. CONSTITUTION:An aqueous suspension of polyvalent metallic compound of co condensed salicylic acid resin having superior quality can be obtained by using such salt of the sulfonated styrene maleic acid polymer as a dispersant for dispersion of said metallic compound into fine particles by a wet method, as shown by the formula I. In the formula, (m) represents integers of 1-5, (n) 5-10,000, X also represents Na, K, Cs, Li, Rb or NH4. A preferable highly effective dispersant has a mol ratio of 1:1-5:1 for the styrene sulfonic acid group to the maleinic acid group and a comparatively low molecular weight of 1,000-100,000 of copolymer. A pressuresensitive copying paper prepared by using an aqueous coating solution which contains the aqueous suspension has an improved color developing property and a low thickening tendency of aqueous paint. Subsequently, foaming at the time of aqueous paint circulation is significantly restricted, thus showing high coating stability.
