Abstract: A sustained release pheromone-containing preparation is obtained by incorporating a sex pheromone having a heat of evaporation ranging from 21,000 to 27,000 cal/mole and a parameter, as a measure for the solubility, ranging from 8 to 9 cal.sup.1/2 cm.sup.-2/3 into powder of a synthetic resin, whose parameter, as a measure for the solubility, ranges from 8 to 9.5 cal.sup.1/2 cm.sup.-2/3, having an average particle size ranging from 0.2 to 2.5 mm. The sustained release pheromone-containing preparation can be sprayed using a widely used spraying machine and can release the sex pheromone at an almost constant concentration over a long period of time.

Abstract: Active agent-containing printing ink which contains fine particles of thermoplastic polymer containing an active agent. The effect of active agent contained in a printed matter can be properly and effectually produced for a long period of time without causing undesirable release or deterioration of the active agent in printing and uses.

Abstract: A preserving material of a layered structure which is composed of an impregnated absorbent sheet containing a preserving liquid and impermeable barrier films being bonded to both surfaces of the adsorbent sheet. The effective components of the preserving liquid is evaporated gradually from the peripheral edges of the preserving material.

Abstract: An improved electroconductive coating material containing electroconductive organic fiber of 10.sup.2 .OMEGA..multidot.cm or lower in specific resistance, and preferably the organic fiber is 0.1 to 5 mm in length and 2 to 500 in aspect ratio. The coating material of the invention can form an improved uniform coating film which is excellent in electroconductivity and anti-static property, and it is hardly peeled off with maintaining its advantageous properties for a long period of time.

Abstract: An active agent-containing laminated material and the method for producing the same, in which an impermeable film is temporarily adhered to at least one side surface of an active agent-containing film and impermeable film can be peeled off and readhered repeatedly. The laminated material is prepared by directly laminating a molten web of active agent-containing polyolefin composition with an impermeable film at and pressing them together, said active agent-containing polyolefin composition comprising: (A) 10 to 100 parts by weigh to carboxyl group-containing ethylene based copolymer of at least 7% by weight in the content of carboxyl group-containing monomer; (B) 90 parts by weight or less of low density polyethylene having a melt index of at least 30 g/10 min.; and (C) at least 0.005 parts by weight of an active agent or agents relative to 100 parts by weight of said polymers (A) plus (B).

Abstract: A method for producing a laminated material giving higher adhesive strength of laminated layers and the thermal deterioration of polyolefin and the undesirable release of the active agent during the lamination process are avoided. The method is characterized in that the substrate sheet is previously laminated with a polyolefin layer, and a molten web of polyolefin film is laminated to the side of said polyolefin layer of the substrate sheet under pressure at a relatively lower temperature.
