    摘要: A photoresist composition, and a process for using the same are; the composition comprises a polyphenolic resin and a sensitizer effective, when exposed to actinic radiation, to provide alkali solubility to said composition, wherein said resin is represented by the formula (I) or (II): ##STR1## wherein R is a hydrogen atom, a halogen atom, an alkyl group, an alkoxy group, an alkaryl group or an aryl group; R' is a silyl group; and n and n'+m are greater than 3. The composition exhibits high thermal and plasmal resistance and good dissolution characteristics.

    摘要: Formaldehyde-free resins of the formula (I): ##STR1## where n is an integer greater than or equal to 2, the phenolic units of the resin are directly bonded to one another through positions ortho or para to the hydroxyl group, Y is present at a position meta or para to the hydroxy group and is selected from the group consisting of an alkyl group, a halogen atom, an aryl group, a phenylalkyl group, an allyl group, a carboxyl group of the formula --COOR, where R is a hydrogen atom, an alkyl group or a phenylalkyl group, an amino group of the formula --NR.sub.1 R.sub.2 where R.sub.1 and R.sub.2 are the same or different and represent a hydrogen atom or an alkyl group, and Z is a hydrogen atom, an alkyl group, a halogen atom, an aryl group, a phenylalkyl group, or a --COOR group, or Z in conjunction with the adjacent meta position forms a condensed benzene ring; or a metal-modified, formaldehyde-free phenolic developer resin obtained by reacting said developer resin with a metal salt; the resins are useful as developers in forming colored images by reaction with substantially colorless electron-donating compounds.

    摘要: Peroxidase can be recovered from seed hulls in an improved method using a freeze-thaw technique. First, the seed hulls are comminuted, placed into water and homogenized. Next, the homogenate is frozen then thawed. The enzyme is then recovered from the aqueous solution by conventional means. Soybean or rice seed hulls can be used in this process.
