    摘要： A method for making an opacity relevant grade paper or paperboard product, such as a communication type paper used for printing and writing applications, utilizes an effective amount of quaternized alkanolamine fatty acid ester compounds as an opacification aid to control the optical properties of the paper or paperboard product as a wet-end additive to a papermaking operation. Using the quaternized alkanolamine fatty acid ester compound can improve the opacity of the paper or paperboard product, maintain the opacity of the paper while reducing the use of other opacification aids, such as inorganic fillers and/or pigments, and allow for a reduction in paper grammage without a compromise in opacity. The improvements in paper optical properties are achieved without adversely affecting other characteristics of the paper product such as bulk value, tensile strength, tear index, and the like.

    摘要： A transparent, non-stratified, three dimensional resin reinforced fibrous sheet and the process for its preparation is disclosed. A fibrous sheet is impregnated or coated with one or more tri or higher functional monomers that can be polymerized in-situ to form three dimensional polymer resins, in close contact with the fibrous material of the sheet. A transparentized fibrous sheet results which is resistant to water and alcohols, highly and evenly translucent and useful as tracing media vellum as well as a translucent base for sensitizing with reprographic coatings.
