  • Patent number: 10351724
    Abstract: Coating formulations for improving hide and holdout without sacrificing adhesion on cementitious substrates are provided. The coating formulations can achieve high hide and holdout with a low pigment volume concentration by utilizing particles with pre-selected oil absorption and particle size range. The coating formulations can be used as a functional for fiber cement substrates. When applied in combination with a top coat, the functional provides provide high hide and hold and enhanced adhesion while reducing pigment loading.

  • Patent number: 5126230
    Abstract: Compositions and methods for developing quinone diazide positive-working photoresists. The compositions consist essentially of an aqueous solution of a tetraalkylammonium hydroxide and an adjunct having a structure selected from: ##STR1## wherein n is 0 or 1; m is 1 or 2; and each R.sup.1 and R.sup.2 is independently selected from hydrogen, methyl, or ethyl, but in Structure I the two R.sup.2 's are not both ethyl. The methods involve use of this composition to develop the indicated photoresists. The addition of an adjunct of the indicated type prevents the formation of irregular deposits on the edges of unexposed portions of the photoresist lines when the photoresist is developed. Selection of these adjuncts also increases the uniformity of line widths of photoresist lines developed according to the present invention, and increases the process latitude of the developer.

  • Patent number: 4808513
    Abstract: Compositions and methods for developing quinone diazide positive-working photoresists. The compositions consist essentially of an aqueous solution of a tetraalkylammonium hydroxide primary alkali and an alkanolamine having the following structure: ##STR1## wherein n is zero or 1, and each R is independently selected from hydrogen, methyl, or ethyl. The methods involve use of this composition to develop the indicated photoresists. The addition of an alkanolamine of the indicated type prevents the formation of irregular deposits on the edges of unexposed portions of the photoresist lines when the photoresist is developed. Selection of these alkanolamines also increases the uniformity of line widths of photoresist lines developed according to the present invention, and increases the process latitude of the developer.
