    摘要： A process for forming a resist pattern comprises the steps of applying on a substrate to form a photosensitive resist layer a photosensitive composition comprising at least one photosensitive compound having, in the molecule, two or more structural units represented by C6R2-6—CHR1—OR7 or C6R2-6—CHR1—COOR7 where R1 is a hydrogen atom or an alkyl group, at least one of R2, R3, R4, R5, and R6 is a nitro group, and others are selected from the group consisting of a hydrogen atom, a halogen atom, an alkyl, an alkoxy, a phenyl, a naphthyl, and an alkyl in which a part or the entire of hydrogen atoms are substituted by a fluorine atom, and R7 is a substituted or unsubstituted phenylene or naphthylene group dissolved in an organic solvent, irradiating the resist layer selectively with a radiation ray, and developing a portion irradiated by the ray to form a pattern of the resist layer.

    摘要： .alpha.-Hydroperoxyisopropylphenyl compounds are useful as an organic hydroxyperoxide content in test compositions for the measurement of peroxide-active substances and are effectively utilized for detecting peroxide-active substances such as blood or hemoglobin (occult blood).Test devices for the detection of occult blood are constituted of a carrier in which organic hydroperoxide, coloration indicator, buffering agent, wetting agent, activating agent and stabilizer are impregnated. If hemoglobin is present in a specimen, the organic hydroperoxide is activated to produce nascent oxygen with which the indicator is oxidized and develops color. Although 2,5-dimethylhexane-2,5-dihydroperoxide and cumene hydroperoxide have been employed as the organic hydroperoxide, they are disadvantageous in remarkable reduction of the detective sensitivity due to lack of the stability with elapse of time, pseudonegative judgement when vitamin C is contained in urine specimen, reduction of capacity in the multi-item test pieces for the detection of urinary components caused by discoloration of the adjacent test pieces, low coloration sensitivity, etc.The compounds of the present invention are improved in the above-mentioned defects.As typical examples of the .alpha.-hydroperoxy-isopropylphenyl compounds according to the invention are mentioned 4-(2,4,7-trioxaoctyl) cumene hydroperoxide, 4-(.alpha.-operoxyisopropyl)benzyl benzyl ether, 4-octyl cumene -hydroperoxyisopropyl)benzyl benzyl ether, 4-octyl cumene hydroperoxide, bis[4-(.alpha.-hydroperoxyisopropyl)benzyl]ether, N,N-dimethyl-]4-(.alpha.-hydroperoxyisopropyl)benzene]-sulfoamide and the like.
