Abstract: There is provided an optical member having an optical material and a tacky layer provided on at least one surface of the optical material. The tacky layer has an initial adhesive force of not smaller than 400 g per 25 mm based on 90° peeling from a resin substrate and has an adhesive force of not larger than 1000 g per 25 mm after heating at 70° C. for 5 hours. There is also provided a cell substrate made of a resin substrate. The resin substrate has an initial adhesive force of not smaller than 400 g per 25 mm on based on 90° peeling from the tacky layer provided on the optical material and having an adhesive force of not larger than 1000 g per 25 mm after heating at 70° C. for 5 hours. And there is provided a liquid-crystal display in which the optical member is adhesively bonded through the tacky layer of the optical member to the surface of a liquid-crystal cell formed by used of the cell substrate.

Abstract: A sheet for protecting paint film comprising a support having formed thereon a rubber adhesive layer comprising an isobutylene polymer having a degree of dispersion of from 1 to 2.3 and a weight average molecular weight of 300,000 to 600,000 (the domain A in the FIGURE) as the base polymer.The paint film protecting sheet has the compatibility of the prevention of the occurrence of a microdeformation and a good peelability. That is, when an article such as automobiles having a paint film applied with the protecting sheet is placed outdoors for a long period of time at high temperature, the paint film is hard to deform and the sheet can be easily peeled even after adhering for a long period of time.

Abstract: A method for protection of a plant from damage caused by an insect pest of the order Lepidoptera and Diptera is disclosed. An insect controlling agent having an active component of an insecticidal crystal toxin produced by Bacillus thuringiensis var. kurstaki No. 145 FERM BP-3905, No. 161 FERM BP-3906, and No. 116 FERM BP-3907 is used in the method for protection of a plant. The insecticidal crystal toxin has a set of molecular weights as determined by 10% SDS-polyacrylamide gel electrophoresis of 125,000 daltons and 60,000 daltons when produced by No. 145, 130,000 daltons and 60,000 daltons when produced by No. 161, and 130,000 daltons and 60,000 daltons when produced by No. 116.

Abstract: A novel 3(2H)-pyradazinone derivative of the formula (I) ##STR1## wherein, R represents an alkyl group having 1 to 4 carbon atoms substituted by a cycloalkyl group having 3 to 8 carbon atoms, an alkyl group having 1 to 4 carbon atoms substituted by a phenyl group which may be substituted or an alkyl group having 1 to 4 carbon atoms substituted by a heterocyclic group, R' represents a hydrogen atom, a halogen atom, an alkoxy group having 1 to 4 carbon atoms or a hydroxyl group having 1 to 4 carbon atoms, J represents any of various organic radicals. There is also provided a process for preparing said derivatives. These derivatives are useful as active ingredients of insecticidal, acaricidal and/or nematicidal compositions for agricultural and horticultural uses as well as of expellent compositions for pests parasitic on animals.

Abstract: The present invention provides novel strains of Bacillus thuringiensis var. Kurstaki, No.145, No.116 and No.161.These strains produce an insecticidal crystal toxin which is useful as an active component in a insect pest-controlling agent.

Abstract: The present invention provides novel uracil derivatives and pesticides which contain the novel uracil derivatives as an active ingredient, and exhibit preventing and controlling effects against harmful living things, especially agricultural insect pests, sanitary insect pests, stored product insect pests, house insect pests and veterinary insect pests at a very low drug-concentration.
