  • Publication number: 20050043441
    Abstract: The invention relates to a latex that may be utilized as a binder for nonwoven applications to form a permeable sublayer of personal hygiene articles. The latex is prepared by a process including the steps of (1) polymerizing a monomer mixture comprising styrene, itaconic acid, surfactant and water soluble free radical initiator to form a seed; (2) sequentially adding equal increments of a monomer mixture of styrene, butadiene and acrylic acid to the seed under emulsion polymerization conditions to form a styrene-butadiene-acrylic acid copolymer; and then (3) neutralizing the styrene-butadiene-acrylic acid copolymer to a pH of about 4.5 to 7 to form the latex.

  • Patent number: 5942556
    Abstract: Disclosed is a radiation curable composition which includes: (a) an unsaturated ester compound, and (b) a pulverizable vinyl ether compound. The unsaturated ester compound is characterized as having a plurality of unsaturated ester groups per molecule. The pulverizable vinyl ether compound is characterized as including at least one of the following: (a) a compound having an average of greater than 1.0 reactive vinyl ether groups per molecule, and (b) a vinyl ether-containing group bonded to the unsaturated ester compound such that there is an average of at least 1.0 reactive vinyl ether group per molecule. The unsaturated ester compound, the vinyl ether compound and/or a mixture thereof is treated with a reducing agent so as to decompose destabilizing agents present therein that would initiate premature polymerization of the vinyl ether compound.

  • Patent number: 5585415
    Abstract: Very low gloss finishes are attained in pigmented, radiation curable coatings by inclusion of a combination of photoinitiators having an acylphosphine oxide photoinitiator and a second photoinitiator such as an acetophenone derivative. In the method of producing the low gloss finishes, the coating is first exposed to ionizing radiation (e.g., electron beam) in air, then exposed to actinic radiation (ultraviolet light) in an essentially inert atmosphere. The low gloss is achieved by a fine, uniform surface wrinkling effect.

  • Patent number: 4314923
    Abstract: Coating compositions are formulated using a polyol with a hydroxyl functionality of at least three modified by reaction with a glycidyl ether in proportion of about 0.1 to about 4, preferably from about 0.2 to about 2 moles of glycidyl ether per mole of polyol, with which is combined, as curing agent, a compatible aminoplast resin. When the polyol is trimethylol ethane, for example, and is so modified with allyl or butyl glycidyl ether, for example, and is so modified with allyl or butyl glycidyl ether, for example, and the compositions contain a methylated melamine formaldehyde condensate as curing agent, they are especially suitable for clear top coating surfaces of wood or flat woodstock containing printing inks to simulate woodgrain, to provide a durable coating highly adherent to the inks as well as the cellulosic materials. The compositions may contain high solids content yet they are stable on storage without development of crystallization and are reducible or thinnable with water.
