Abstract: A ligneous finishing material including a base plate, a sheet formed from a sheet base impregnated with a thermosetting resin and attached to the base plate, and a decorative sheet impregnable with a resin and attached to the sheet. The base plate, sheet and decorative sheet are laminated on each other by a hot-press process. The thermosetting resin is preferably a phenol resin having a fluidity in a pre-pregnated state of 3% to 50%. The ligneous finishing material is inexpensive and highly resistant to surface damaging, and can be used as a surface facing material for floors, etc., and as a facing material for fittings and furnishings.

Abstract: A particular organic boron compound is compounded with rubber or applied to the surface of the steel cord in order to improve the resistance to corrosion fatigue of steel cord as a reinforcement for rubber articles with holding good adhesion properties to rubber.

Abstract: A rubber composition for tires having improved heat build-up and high temperature reinforcibility comprises specified amounts of particular surface-treated carbon black, silica and particular silane coupling agent based on 100 parts by weight of rubber ingredient.

Abstract: A rubber composition comprising 30-140 parts by weight of carbon black treated with a particular compound based on 100 parts by weight of rubber which provides an improved reinforcement property of the rubber composition and at the same time improvement of the efficiency of productivity in tire manufacturing.

Abstract: A dispersion improved carbon black compounded rubber composition comprises a rubber component and a reinforcing carbon black in an amount of from 30 to 150 parts by weight with respect to 100 parts by weight of the rubber component. The rubber component is selected from a group consisting of a natural rubber, synthetic isoprene rubber and a mixture thereof, or a blend of this rubber component with a diene base synthetic rubber other than this rubber component. The reinforcing carbon black has a specific surface area of from 70 to 200 m.sup.2 /g when measured by a nitrogen adsorption method and a DBP value of from 80 to 130 ml/100 g, and is obtained by introducing mainly phenolic hydroxide groups into the surface of the carbon black through plasma treatment at low temperatures or by introducing carboxyl groups and the phenolic hydroxide groups thereinto through plasma treating at low temperatures and neutralizing the thus introduced acid groups.

Abstract: A rubber composition for use in a tire tread comprising (a) a polyisoprene rubber or a polyisoprene rubber and a synthetic rubber, (b) a denatured nitrosoquinoline compound and (c) carbon black.

Abstract: A composite material of steel cords and rubber having improved corrosion fatigue resistance and fretting fatigue resistance and a method of producing the same are disclosed. The composite material is produced by bonding rubber to steel cords through vulcanization. Before the vulcanization, steel cords are treated with a rust preventing material consisting of at least one particular surfactant and at least one particular film-former to form a protect layer on the surface of the steel cord.
