Title
(EN) DRY ERASE ARTICLE
(FR) ARTICLE D'EFFACEMENT À SEC
Abstract
(EN) Dry erase articles are described comprising a writable surface layer comprising a cured hardcoat composition comprising the reaction product of certain low surface energy compound(s). In one embodiment, the compound(s) comprise a C18-C36 hydrocarbon group and an ethylenically unsaturated group. In another embodiment, a mixture of compounds is utilized, the mixture comprising first compounds comprising a C18-C36 hydrocarbon group and an ethylenically unsaturated group and second compounds comprising a C8-C17 hydrocarbon group and an ethylenically unsaturated group, wherein the first and second compound are present at a weight ratio of 3:2 to 4:1.
(FR) L'invention concerne des articles d'effacement à sec comprenant une couche de surface inscriptible sur laquelle se trouve une composition de revêtement dur durcie comprenant le produit de réaction d'un ou plusieurs composés à faible énergie de surface. Dans un mode de réalisation, le ou les composés comprennent un groupe d'hydrocarbures de C18 à C36 et un groupe à insaturation éthylénique. Dans un autre mode de réalisation, un mélange de composés est utilisé, le mélange comprenant des premiers composés incluant un groupe d'hydrocarbures de C18 à C36 et un groupe à insaturation éthylénique et des deuxièmes composés incluant un groupe d'hydrocarbures de C8 à C17 et un groupe à insaturation éthylénique. Le premier et le deuxième composé sont présents dans un rapport massique de 3:2 à 4:1.
