    摘要： This disclosure is directed to mark-forming record material containing two essential color-forming reactants which produce color upon contact with one another in the presence of a mutual liquid solvent wherein (A) one of said color-forming reactants is a phenolic resin containing at least 70 percent, by weight, of oil-soluble, amorphous, free-hydroxy-group-containing, roomtemperature-solid, thermoplastic polymeric condensates of formaldehyde and at least one p-substituted phenol of which at least 10 percent, by weight, is a p-substituted phenol wherein the p-substituent is electron-attracting (for example, a p-halosubstituent), said polymeric condensates containing at least three p-substituted phenol units per molecule, and wherein (B) the other essential color-forming reactant is a basic chromogenic material; for example, Crystal Violet Lactone. The polymeric condensates of (A) may be a mixture of polymer chains, each polymer chain having three or more of the same or different recurring p-substituted phenol units per molecule with methylene bridges between adjacent p-substituted phenol units. Where the polymer resin of (A) is not entirely composed of condensates having recurring phenolic units bearing p-electron-attracting substituents, the remaining recurring phenolic units bear pelectron-donating substituents; for example, p-alkyl substituents. A preferred form of mark-forming record material combines in the same polymeric resin, either in the same molecule or in a mixture of molecules, phenolic units bearing electron-attracting and donating substituents; for example, a phenolic resin having phalo groups as the electron-attracting substituents and p-alkyl groups as the electron donor substituents. By so blending electron-attracting and -donating groups, a ''''balanced'''' condensate (or mixture of condensates) having improved properties as a record material is achieved.

    摘要： A resin coated sand for shell-molding foundry operations having improved shake-out properties for molds prepared therefrom is disclosed. Also disclosed are methods of producing said sand. The foundry aggregates or sand are coated with a phenolic resin containing from 0.2 to 40 parts of an aromatic nitro compound per 100 parts of phenolic resin. The resin may be a novolac type, a resole type or a mixture of the two types of phenolic resins. Suggested aromatic nitro compounds are nitrophenols, dinitrophenols and nitronaphthalenes. The process is extremely useful for coating lower melting temperature metals such as aluminum and magnesium.
