    摘要： Provided are aqueous paints with which paint films which have excellent paint film properties such as water resistance and resistance to chemical attack, and excellent finished appearance are obtained, and which have excellent painting operability and storage stability. The invention further provides water dispersible acrylic based graft copolymers, aqueous paints incorporating same and a method to make such paints, wherein an unsaturated bond-containing acrylic based copolymer (a) obtained by reacting an acrylic based copolymer (a1) of acid value 35-120 mg.KOH/gram, hydroxy group value 50-150 mg.KOH/gram, glass transition temperature -20.degree.-+50.degree. C. and number average molecular weight 4500-9000 and an unsaturated monomer mixture (a2), which has functional groups which can react with hydroxy groups, in a mol ratio of a2/a1=0.4-1.5, and a monomer composition (b) compounded in such a way that the acid value is not more than 15 and the hydroxy group value is 50-150 are reacted in the proportions by weight of a/b=10/90-60/40 to produce the claimed water dispersible acrylic based graft copolymer.

    摘要： A process for preparing polymer non-aqueous dispersions to be formulated together with a binder component in coating compositions, which comprises the steps of: (1) emulsion polymerizing a hydroxy group containing .alpha.,.beta.-ethylenically unsaturated monomer, a polyfunctional .alpha.,.beta.-ethylenically unsaturated monomer and an .alpha.,.beta.-ethylenically unsaturated monomer different therefrom by using a water-soluble polymerization initiator, preferably a persulphate, in a soap free system or in the presence of an ester group containing anionic or cationic surfactant; adding an organic solvent, preferably comprising an amphipathic organic solvent, to a resultant polymer aqueous dispersion; and then adding a basic compound catalyst when the anionic surfactant is used or an acidic compound catalyst when the cationic surfactant is used, to thereby hydrolyze completely said surfactant and water-soluble polymerization initiator at a temperature not exceeding 95.degree. C. as in the condition of suspension; (2) adding an acidic or basic compound to said suspension to neutralize said basic or acidic compound catalyst: then after adding dispersion stabilizing resin, further adding an amine salt of organic acid, followed by leaving said suspension to stand to separate into organic and water layers; and isolating the organic layer from the water layer; and (3) removing residual water in the organic layer. The resultant polymer nonaqueous dispersion comprises polymer particles having a total ionic group concentration (I) less than 2.times.10.sup.-5 mol/g particle, a hexane tolerance (HT) from 5 to 40 exclusive and a degree of swelling in acetone (S) less than 10, and used with a binder component comprising a polyol resin and a curing agent for preparing coating compositions.

    摘要： A lubricating oil supply apparatus for a hydraulically operated vehicular transmission has a lubricating oil passage for supplying oil discharged from a discharge port of a pressure control valve which is provided in a hydraulic control circuit of the transmission to lubricating portions thereof as lubricating oil. The lubricating portions are divided into a plurality of groups depending on a change in a required amount of lubricating oil due to a temperature of the transmission. The lubricating oil passage is branched into a plurality of branches corresponding to the groups. The lubricating oil supply apparatus has a choke type of throttle which is disposed in at least one of the branches of the lubricating oil passage.
