    摘要： A laminated game racket frame having a closed hoop-shaped inner frame and an outer frame with the outer part of the inner frame integrally bonded to the inner part of the outer frame to form a unitized body, each frame being formed as a laminate comprised of a plurality of strips. Some of these strips are made of wood, thermoplastic resin or metal, and some are made as laminates themselves from plies of reinforced thermosetting resins.

    摘要： A substantially colorless bisfluoran chromogenic material having the structural formula ##STR1## wherein R.sup.1 and R.sup.2 each represent an alkyl group;X and Y each represent a hydrogen atom, a halogen atom, an hydroxyl group, an alkyl group, a nitro group, an amino group, an acyl group, or a carboalkoxy group;Z represents an oxy radical, a carbonyl group, an alkylene group, an alkylidene group, a sulfonyl group, or a thio radical; andn represents an integer from 0 to 1.The bisfluoran compounds are produced by reacting a 4-dialkylamino-2-hydroxy-2'-carboxybenzophenone with a diphenol wherein the diphenol is unsubstituted in at least one of the positions ortho to an hydroxyl group in each of the phenyl rings. The bisfluorans are used in pressure-sensitive copy systems comprising a support bearing microcapsules containing the bisfluorans, alone, or in combination with other color-forming materials.
