Abstract: A method for reinforcing a concrete structure is disclosed in which the steps of (a) applying to a long fiber prepreg an adhesive, (b) attaching on the surface of the concrete structure the long fiber prepreg with the adhesive interposed between the surface of the concrete structure and the long fiber prepreg, and (c) curing the thermosetting resin at an ambient temperature are performed. The long fiber prepreg has as a matrix a thermosetting resin with a curing temperature of 70.degree. C. or above. The adhesive has a curing temperature of from 10.degree. to 40.degree. C., and accelerates the curing of the thermosetting resin impregnated in the long fiber prepreg.

Abstract: A process for producing a dimensionally stable polyolefin molding, characterized by using a specific compound or a mixture thereof with at least one ordinary pigment, the specific compound being obtained by reacting a halogenated phthalic compound with hydrazine or an organic diamine.

Abstract: A copper phthalocyanine pigment composition consisting essentially of 100 parts by weight of copper phthalocyanine and 0.5 - 30 parts by weight of a copper phthalocyanine derivative having the following formula ##STR1## WHEREIN Cu--Pc-- is the residue of copper phthalocyanine, m and n are each an integer of 1 - 4, and R.sub.1 and R.sub.2 are each a substituted or non-substituted alkyl group or a heterocyclic group containing the nitrogen atom appearing in the formula.
