In a process for producing a color television picture tube which comprises at least the step of coating phosphor slurries onto the inner surface of a panel to form a phosphor layer, the step of forming two layers each consisting of an aqueous filming emulsion containing an acrylic resin, the step of forming a metal film on the second layer, and the step of baking out the organic substances, a color television picture tube having a metal film which contains a few pores and cracks and no blister can be produced by using said phosphor slurries containing an acrylic resin and using the first aqueous filming emulsion containing an acrylic resin having an elongation of 10% or more and using the second aqueous filming emulsion containing an acrylic resin having an elongation of less than 10%.
