Phosphorescent marking paint, useful e.g. in road signs, comprises aggregates (e.g. cristobalite) previously coated with phosphorescent pigment (e.g. strontium sulfide) and a first binder (e.g. polyurethane)

摘要

Phosphorescent marking paint comprises at least aggregates (1) previously coated with phosphorescent pigment and a first binder (3). Independent claims are included for: (1) a non-skid marking (7) obtained by applying the paint on a surface such as road, where the marking has asperities (8) comprising the aggregates coated with phosphorescent pigments, on its surface; and (2) preparing a marking based on at least one aggregate and a binder on a support (6), comprising: coating the aggregates with the phosphorescent pigments; depositing a layer of binder on the support; and sprinkling the binder layer with pigmented aggregates.
