soluble resins after completion of the reactions and optional heating the laked monoazo red pigments are recovered from the water based reaction slurry by filtering to form a presscake of pigment which is washed with hot water e g from about 40 u00b0 c to about 70 u00b0 c so as to remove the excess acids bases and unwanted salts formed during the coupling reaction the presscake is typically washed with from about 10 to about 20 times its volume of water the filter cake is generally washed until the filtrate gives only a slightly positive test for chloride ion the washed presscakes can be dried ground and used in the form of a coarse or finely divided powder alternatively the laked monoazo red pigments of this invention can be dispersed into oleoresinous vehicles to prepare flushed bases or dispersed into aqueous or organic vehicles to prepare aqueous dispersions or organic pigment compositions the laked monoazo red pigment of the present invention comprises a compound represented by the following formula i in another embodiment the laked monoazo red pigment of the present invention consists essentially of the compound represented by formula i that is an essentially pure laked monoazo red pigment represented by formula i the present invention also relates to pigment compositions containing a major amount of the laked monoazo red pigment represented by formula i and a minor amount of an amine surfactant in another embodiment the pigment compositions consist essentially of a major amount of the laked monoazo red pigment represented by formula i and a minor amount of at least one of an amine surfactant and a sulfosuccinate surfactant that is an essentially pure mixture of the laked monoazo red pigment represented by formula i.
