I. I. DU PONT PE NEMOURS & CO. Pigment? Department CC: M. J. McLain/L. P. Andrew?, Wilmington C. I. Smith, Jr., Wilmington A. A. Brlzzolara J. Jackson P, D. GRAHAM PIGMENTS WILMINGTON '/NEWARK, NEW JERSEY JULY 19. 1962 -V Y-662-D In our telephone conversations today you advised that IPX was on the verge of adopting a new Imperial Medium Yellow, X-2904, in place of our Y-662-D. This represents a potential loss of 400,000 Its/year of business. IPI reports that the com petitive Is equal to Y-469-P in light stability and satisfactory in reactivity m Vaposet. We immediately plan to start study on developing a counteroffering. To aid, we need the following help from Sales: 1. A sample of the competitive. Eventually we may need up to 10 lbs. We must find out if the competitive is truly equal to Y-469-D in light stability and fully equal to Y-662-D in reactivity and In what vehicles. If it does combine all these properties. It Is an outstanding product. If, however, they have obtained the better llghtfastness at the expense of some of the reactivity properties, the problem of developing a match will not be so complicated. We also require a sample so that it can be analysed for composition. 2. We would also appreciate Sales developing the information from IPI If this product shows good reactivity performance In other vehicles, such as K-6, as well as In Vaposet. If these products are now used only in Vaposet, the problem of developing a better llghtfast product with good reactivity is considerably simplified. 3. We should also like to know if IPI considers the competi tive to be equal to Y-662-D in reactivity or whether it is ade quate but not as good as Y-662-D. If it is not quite as good In reactivity. It again represents a compromise In properties. We will appreciate your obtaining this information and a sizable sample as soon as possible. Rf.l CA. HJf&EMAN TECHNICAL SUPERVISOR N39930
