Patent number: 5656679Abstract: This invention relates to improved water-soluble acrylic latex compositions. In particular, this invention relates to acrylic latex compositions produced by reacting monomers with water-soluble support resins derived from reacting a modified rosin with an alkanolamine containing at least one secondary amine and at least one hydroxyl group. These acrylic latex compositions can be utilized to produce water-based flexographic and gravure ink formulations.Type: GrantFiled: May 17, 1996Date of Patent: August 12, 1997Assignee: Westvaco CorporationInventor: G. Frederick Hutter

Patent number: RE36458Abstract: Vinyl heat welding rod for seam sealing vinyl resilient flooring, whether in sheet or tile form, are used to obtain a homogeneous, monolithic appearing surface. This rod is specifically made to duplicate the appearance of the flooring material. For a chip-image flooring structure, a sheet of multicolored chips having a similar, but different formulation from that of the flooring material is prepared and the sheet is cut into suitable strips, heat pressed in a rod mold, end adhered or further molded to form the desired length, and used as a vinyl heat welding rod for sealing seams in flooring. Thus, the chip pattern is evident in the seam area and does not appear different when compared to the adjacent surface.Type: GrantFiled: August 15, 1997Date of Patent: December 21, 1999Assignee: Armstrong World Industries, Inc.Inventors: Edwin J. Quinn, Manuel A. Velez, Richard M. Ringer, Michael E. Buckwalter
