  • Patent number: 5424359
    Abstract: Disclosed is a thermoplastic resin composition comprising(A) 90 to 10% by weight of a modified polyolefin type resin obtained by subjecting 100 parts by weight of a polyolefin type resin to graft polymerization with 0.01 to 20 parts by weight of an .alpha.,.beta.-unsaturated carboxylate having a hydroxyl group and 0.01 to 50 parts by weight of an aromatic vinyl compound; and(B) 10 to 90% by weight of a saturated polyester.

  • Patent number: 5324225
    Abstract: An interactive novelty figure includes a housing having an external configuration that can simulate, for example, an animal. A plurality of switch assemblies is located about the housing and are obscured within its exterior configuration to respond to certain predetermined stimuli, such as pressure and sound. A sound-generating circuit and a motor for moving an appendage member, attached to the housing, is provided within the housing. Different sounds, characteristic of the animal, can be provided in response to both pressure and audio commands. The appendage member can further comprise a pair of parallel elongated members that can flex to provide a life-like wagging motion.

  • Patent number: 4740450
    Abstract: An image reproducing material which comprises a support and at least a photosensitive resin layer and scratch resistance layer borne on the support, said scratch resistance layer containing a compound represented by AmBn, wherein A is mono- or divalent, straight or branched C.sub.11-20 aliphatic hydrocarbon; B is hydrogen, hydroxyl, amino, nitrile, aldehyde, carboxyl, or alkylamide, alkylester, ammonium salt or a periodic table group I-IV metal salt of a carboxylic acid; m is an integer of 1 to 3; and n is 1 or 2. A process for preparing the image reproducing material as well as a process for preparing an image reproduced material by using the image reproducing material are also described.

  • Patent number: 4699859
    Abstract: A reducible image-containing element which comprises a support material and a photopolymerized layer provided thereon, said photopolymerized layer having an image area which is cured at the upper part and not cured at the lower part, said non-cured lower part containing at least one of polyvalent phenols and their derivatives in an amount effective in preventing said non-cured lower part from curing.

  • Patent number: 4459349
    Abstract: A photosensitive resin composition which comprises (1) an ethylenically unsaturated compound which can be addition polymerized to form a high molecular compound, said addition polymerizaton being initiated by a free radical and of chain-propagation, (2) a 2-polycyclic aryl-4,5-diphenylimidazolyl dimer wherein the polycyclic aryl group comprises at least two benzene rings condensed each other and (3) at least one compound selected from the group consisting of dimedone, indolacetic acid, N-naphthylglycine, S-lower alkylthioglycollic acid, 4,4'-bis[di(lower)alkylamino]benzyl, p-di(lower)alkylaminobenzoic ester, leucocrystalviolet, indoxylic acid, rhodanine, 7-di(lower)alkylaminocumarine and diarylthiourea and their derivatives, the molar ratio of the component (2) and the component (3) being from 2:1 to 1:5.

  • Patent number: 4419438
    Abstract: An image reproducing material comprising a supporting sheet bearing a metal or metallic compound layer having a thickness of 100 to 1000 .ANG. and a photosensitive resin layer, which is characterized in that said photosensitive resin layer contains (1) an ethylenically unsaturated compound which is polymerizable by the action of free radical and chain propagative, (2) a compound showing photochromism by radical mechanism, (3) a free radical producing agent and (4) an acitinic light absorber. There is also provided an image formed (reproduced) material obtained by patterned exposing the above image reproducing material and then processing the same, a method for obtaining such image formed material and also a method for dot-etching such image formed material. By the use of these materials and methods, dot-etching can be effected easily and there are obtained sharp images without the formation of pin holes.
