Aggregated dyes for radiation-sensitive elements

A dispersion comprising an aqueous medium having dispersed therein an aggregated dye of the Formula (I):

A photographic element contains a filter dye of the Formula (I): ##STR1## wherein R.sup.1 -R.sup.4 each independently represent a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group or a substituted or unsubstituted heteroaryl group; L.sup.1, L.sup.2 and L.sup.3 each independently represent substituted or unsubstituted methine groups; M.sup.+ represents a proton or an inorganic or organic cation.

Coating processes

An apparatus for metering required proportions of different fluid ingredients to make a required mixture (e.g. a colored paint) includes a rack of storage containers for the ingredients, each provided with a valve-controlled outlet and a receiving container mounted on a weighing device which is presentable to a chosen sequence of storage containers in turn to receive the required contribution from each. Metering of the necessary ingredient additions is effected automatically by a valve actuator carried by the support for the weighing device. Data processing control to optimize operation is described.
