    摘要: The present invention is concerned with a process for preventing chemical injuries to vegetables, fruits or flowers caused by methyl bromide, which comprises keeping the vegetables, fruits or flowers, which have been fumigated with methyl bromide, together with (A) an agent for eliminating methyl bromide comprising at least one compound selected from the group consisting of chloric acid, chlorous acid, hypochlorous acid, phosphoric acid, phosphorous acid, hypophosphorous acid and salts thereof and/or (B) an amine. According the present invention, the chemical injuries to vegetables, fruits or flowers caused by methyl bromide can be easily prevented.

    摘要: The present invention relates to a copper foil having a primer resin layer which improves the adhesive strength between a copper foil surface without roughening treatment and a substrate resin and a laminated sheet using the same and is characterized by using a polyimide represented by the following formula (1): (wherein, R1 represents a quadrivalent aromatic group which is a residual group of a dicarboxylic acid dianhydride ingredient (pyromellitic acid anhydride, 3,3′,4,4′-biphenyltetracarboxylic acid dianhydride, 3,3′,4,4′-benzophenontetracarboxylic acid dianhydride or 2,3,6,7-naphthalenetetracarboxylic acid dianhydride), R2 represents a divalent aromatic group which is a residual group of a diamine ingredient (1,3-bis-(3-aminophenoxy)benzene, 3,3′-diamino-4,4′-dihydroxydiphenylsulfone or/and 4,4′-diamino-3,3′,5,5′-tetraethyldiphenylmethane), and n1 represents a repeating number) as a primer resin; and copper foils and laminated sheets having said polyimide layer as a primer have high adhesive strength and are suitable for flexible printed wiring boards.
