The invention relates to a housing for an electrical operating means such as a light, plug-in device, measuring instrument, switch, distributor, or the like, having at least one first and one second housing part that can be assembled with one another in an explosion-proof fashion. The device is for scanning a first information layer by means of a first radiation beam having a first wavelength and a first polarisation, a second information layer by means of a second radiation beam having a second wavelength and a second polarisation, and a third information layer by means of a third radiation beam having a third wavelength and a third polarisation. from 3 to 20 parts by weight of a rubber containing one or more functional groups; and where the total of the parts by weight of I and II is 100; and moldings produced therefrom. An overlaying, non-adhesive barrier layer may be located between a portion of the adhesive layer and an end portion.
