Abstract: The present invention relates to a polymer latex made by free-radical emulsion polymerization comprising polymer particles containing structural units derived from at least one conjugated diene component, whereby said polymer particles comprise at least one hard phase segment having a glass transition temperature (Tg) of at least 50° C. and at least one soft phase segment having a glass transition temperature (Tg) of 10° C. at most, the total amount of hard phase segments being 2 to 40 wt-% and the total amount of the soft phase segments being 60 to 98 wt-% based on the total weight of the polymer particles, whereby the Tg is measured by DSC according to ASTM D3418-03 and said polymer latex having an electrolyte stability determined as critical coagulation concentration of less than 30 mmol/l CaCl2 (determined for a total solids content of the latex of 0.1% at pH 10) that is particularly suitable for the production of dip-molded articles.

Abstract: The invention provides a reflective sheet that comprises a reflective element and that comprises microspheres partially exposed at a major surface of the reflective sheet. The reflective sheet has further been treated with a fluorinated silane compound that has a fluorinated group and a silane group having one or more hydrolyzable groups. The invention also relates to a method of making the reflective sheet involving treating a reflective sheet with a fluorinated silane compound.
