    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 generally non-transparent substrate is rendered substantially transparent, for example at a particular location or locations thereon, by electrostatically depositing finely divided transparentizing particles onto the substrate and then heating those particles to facilitate their flow into the intersticies of the substrate. The transparentizing particles have an optical refractive index that is substantially the same as that of the substrate, and these transparentizing particles have a melting point greater than that encountered during handling and storage and less than the temperature at which the substrate would be damaged.
