Abstract: A shingle having a headlap section and a buttlap section with at least one portion of the buttlap section having a relatively uniform color and another portion of the buttlap section having a color gradient or gradation from light to dark. An illusion of depth or thickness is created on the portion of the buttlap section having the color gradient. The buttlap section defines in part the exposed weather surface of the associated shingle. The relatively uniform color portions may be formed on tabs or dragon teeth and the color gradient formed on a backer sheet disposed beneath the tabs. Openings between adjacent tabs expose the color gradient to view. A plurality of horizontal striations may be used to establish the desired color gradient from light to dark. The amount of tone and contrast may be selected to create the desired illusion of depth or thickness. The amount of contrast may be varied depending upon the color selected for each shingle.

Abstract: The invention provides a thermosettable resin composition comprising (a) one or more thermosettable resins, (b) one or more of curatives, hardeners, and optionally catalysts for the curing of the thermosettable resin in an amount sufficient for the cure of the thermosettable resin, and (c) an effective amount of at least one non-functional cyclophosphazene to render said resin composition, when cured, flame retardant. The non-functional cyclophosphazene contains aryloxy group substitution and does not covalently bond with the resin network. As a result, the non-functional cyclophosphazene does not negatively impact key performance properties such as modulus, thermal stability, dielectric behavior, fracture toughness, moisture uptake or adhesion.
