Abstract: A continuous process for preparing pigmented thermoplastic molding compositions in an extruder, comprisesI) in a first zoneA) metering in from 10 to 99.999% by weight of a thermoplastic polymer into an extruder andII) in a subsequent zone at temperatures below the respective glass transition temperature of the thermoplastic A)B) adding from 0.001 to 60% by weight of a colorant andthen heating the thermoplastic/colorant mixture in the subsequent zones, homogenizing the polymer melt and extruding the resultant mixture.

Abstract: The invention relates to a continuous method for producing dyed thermoplastic moulding materials in an extruder, as follows: I) in a first area, A) 10 to 99.999 wt. % of a thermoplastic polymer is metered into an extruder. II) In a subsequent area, B) 0.001 to 60 wt. % of a dye is added at a temperature below the particular glass transition temperature of the thermoplastic A). In the subsequent areas, the thermoplastic/dye mixture is heated, the polymer melt is homogenised and the resulting mixture is extruded.

Abstract: The invention relates to a method for connecting a moulded part (I) consisting of a thermoplastic polymer A containing colouring agents to a moulded part (II) consisting of a thermoplastic polymer B containing colouring agents by means of laser radiation. According to said method, 1) the laser radiation passes through moulded part (I) at the point to be connected and strikes moulded part (II), 2) moulded part (I) contains at least one colouring agent which absorbs selectively in the visible range of the electromagnetic spectrum, 3) the colouring agents contained in moulded part (I) and the concentrations thereof are chosen in such a way that moulded part (I) is permeable to laser radiation at the point to be connected, 4) the colouring agents contained in moulded part (II) and the concentrations thereof are chosen in such a way that moulded part (II) absorbs the laser radiation at the point to be connected and 5) the colouring agents contained in the two moulded parts (I) and (II) and the proportions thereof are chosen in such a way that moulded parts (I) and (II) are perceived by the human eye as having essentially the same colour.
